Heretofore, the general practice has been to support the radiator'abovethe axis of the engine crankshaft, where it will not interfere with theengagement of thestarting crank with the crankshaft, when the engine isto beof the starting crank. So as not'to interfere with the circulationof cooling medium thru 7 the assembly of heat radiating elements, thelower tank has an upwardly extending portion at the center, in which islocated the startingcrank opening. The arrangement engine hood to bedropped quite low and i tomobile-body design. 7

In the accompanying drawing, 7' illustrat- 1 ing a preferred embodimentof the invention, Figs. land 2 are front and side elevations,"

respectively, of the radiator structure, with parts thereof broken away.i

Referring more particularly to the draw-' ing, a fragmentary outline ofan internal combustion engine,

meral 1, is indicated by broken lines, to the front of which is located,the radiator forming the present subject matter. The radiator may bemounted upon any suitable form of support, which, not constituting anypart of the invention, has not been illustrated.

Following general practice, the radiator comprises an upper tank orheader'2, a lower assemblyof heat radiating elements connecting saidtanks,

Iclaim: A 1. In a radiator of the tubular type, spaced inlet and outlettanks, a series of straight 15 Water flow tubes connecting the" tanks,a'hollow ext-ended portion constituting apart of onetank and projectingat right angles therefrom toward the other tank with its side Walls insubstantial parallelism With the straight Water flow tubes, some of thetubes being longer than others and projecting beside the side Walls ofthe extended portion and therebeyond into communication with the mainportion of the tank and the other tubes term'inating at the end Wall ofand communicating With said extended portion, a series of transverseplates through Which said tubes extend,those plates beyond the extendedportion each being continuous from side to side and receiving all of thetubes and the remaining plates being of shorter length and ending at anadjacent side Wall ofthe extended portion and receiving only longertubes of the tube series, and a lateral passageway through .theextendedtank portion for the insertion of a starting crank or the like.i 2. A heat radiating unit for an automobile radiator or the like,including, a series of straight ater flow tubes adapted to con- 40 nectspaced inlet and outlet tanks,and a series of transverse heat radiatingplates through Which said tubes extend, certain of said tubes andcertain ofsaid plates ending short-of others thereof in-cooperativerelation withioneianother, to provide an open space inthe unit adjacentthe lower end thereof, a bottom tank extending across the lower-ends ofthe tubes and having a riser projecting up into the open space toconnect o with the shorter tubes, and a starting crank opening throughthe riser.
